The website currently makes 3 separate API calls to retreive Death, Confirmed and Recovered cases, however ArcGIS supports multiple queries in one request so the API call has been optimized to retreive all 3 at once.
The endpoint currently only retreives the latest global stats for infection and mortality rates but you could play around with the network console to see how to get more detailed stats
